Screen and chip issue
I owned an MSI GS66 Stealth (with an RTX 3070 Ti and 12th Gen i7). I bought it used, and after some time, lines appeared on the screen. They would come and go, so I took it back to the shop where I bought it. While the laptop was running, the technician decided to disassemble the screen assembly to test it; he connected the panel without the outer casing, and the lines reappeared. There were two technicians there; one moved the screen, and the connection to the laptop cut out, even though the laptop itself remained powered on. Eventually, we discovered the (IC) was faulty. I sent it to another state for repairs, a process that took three months due to the poor conditions in my country. After the IC was replaced, the technician called to say there was another issue. He identified it as a problem with the (chip) and stated that the motherboard needed to be replaced. Is there really no other solution? He only mentioned "the chip"—I’m not sure if there are specific types or variations involved.
